Yes, the IP address does not have a DNS PTR record for it. If its just a
192.168.x.x address (i.e. from the RFC 1918 space), you can add an entry
for it in the /etc/hosts file, and then change the order of /etc/hosts.conf
or add something like
zone "1.168.192.in-addr.arpa" {
type master;
file "db.192.168.1";
};
in /etc/named.conf
and db.192.168.1 has something like
@ IN SOA my.example.com. me.example.com. (
200004060 ; serial
10800 ; refresh after
3600 ; retry after
604800 ; expire after
66000 ) ; minimum TTL
;
; Define the name servers
IN NS my.example.com
;
; Addresses
1 IN PTR my-inside-address.example.com.
